pathetic I only found a pairwise testing service project hosted on Google CodeHttp://code.google.com/p/pairwisetestingservice/source/browseThis project introduces pairwise testing in great detail, including core packages and source code, and a construction orthogonal arrays.ppt and a pairwise testing-orthogonal Arrays Strategy.doc file, the mathematical basis and implementation method of pairwise testing are introduced in detail. In addition, the project was written by Chinese programmers, who

, they do not have any ' knowledge ' of its subsequent nodes, it thinks its children are the same ' excellent ', but the fact is not so, the subsequent nodes are good and bad. Well, that means it is ' close ' to the target node, and if it is treated as a priority, it will find the target node more quickly, thus improving the search performance as a whole. heuristic SearchIn order to improve the above algorithm, we need to expand the following node to

SlemBunk: Android Trojan family targeting Global Bank APP users FireEye's mobile researcher recently discovered a series of Android Trojans, these programs execute a series of malicious behaviors, called "SlemBunk", by imitating valid apps (including 31 banking applications and 2 mobile payment applications) of 33 global financial management institutions and service providers ". Currently, the main impact is in the United States, Europe and Asia Pacific. The SlemBunk program is disguised as a c

firmware interface (UEFI -- the latest version is 2.3.1) is to replace the traditional Basic Input/Output System (BIOS) as the next-generation firmware interface of a PC ). Now, if the system chooses to use the secure boot function, Windows 8 can greatly improve the effective defense capability of rootkit and other malware. With the support of the secure startup function, the operating system can verify the digital signatures of all startup component

Are you still looking for a tool to complete your daily activities, or are you just looking for new tools that you can try to play? No need to worry, because today is your lucky day! Today, I will mention a variety of links, resources and editing tools that can be used for penetration testing, computer forensics, security, and hacking techniques.toolswatch.orgToolswatch.org is maintained by NJ Ouchn (@toolswatch) and Maxi Solder (@maxisoler). This is a cool website where you can find the latest

the number of malware on mobile phones is still very small. To date, less than a few viruses, worms, and Trojans have been discovered that specialize in mobile operating systems . Most cause relatively minor damage, such as file loss, hardware reset, or additional charges. Unfortunately, the threshold for long-term restrictions on malicious attacks is fading. First, the number of mobile device users is growing fast. Second, the market for new, popular

Similarly, or use Baidu Search, click Baidu to provide the connection, but was directed to a random connection, but also the system is infected by virus or malware performance. 2, the browser can not access the Internet Network connectivity is normal, b

unit so that only the adjacent pixels of one vertex share one edge in the vertical direction. This process is described in detail in section 3.2. We use a number of careful design-inspired methods to introduce how to determine whether oblique diagonal pixels are connected. After remodeling, we can determine the visible boundary by comparing the significant differences between adjacent pixels. We specify that these edges are visible because they constitute the visible contour of our final vector

Exploratory testing (exploratory testing) is an important part of agile testing, and its value is different from general testing, such as user story testing or automated testing, which focuses on "unexpected" software flaws, and exploratory testing as a research, heuristic, and solemnity test method is an important complement to general testing. With the popularization of agile testing, exploratory testing has been paid attention to by everyone. This

desktops and laptops because they mistakenly believe that this technology can actually provide more protection. Whether FDE is suitable for an enterprise's system depends entirely on the threats that the enterprise tries to block: loss or theft of devices, theft of server data, operating system tampering, or access of sensitive data by malware, this is the four application scenarios that FDE is good at dealing. Scenario 1: prevent loss or theft of co

"Self-explosive" virus Rombertik: Multi-Level obfuscation, high complexity, and automatic hard drive erasure during analysis Rombertik is a highly complex virus (malware) that uses multi-level obfuscation, highly complex escape detection technology, and anti-analysis technology, in addition, the malware can erase hard disk data to prevent others from analyzing the data. In addition, it can collect all inf

Security researcher Jonathan Brossard created a conceptual verification hardware backdoor called Rakshasa, which is said to be able to replace the computer's BIOS (Basic Input/Output System) and endanger the operating system at startup, but it does not leave any trace on the hard disk.Brossard is the CEO and security research engineer of Toucan systems, a French security company. He demonstrated how the malware works at the Defcon hacking conference o

Security is the foundation of Windows Vista architecture. With Windows Vista, you'll be able to connect to any user you want to connect to, and do whatever you want, and believe that Windows Vista guarantees your information and your computer's security. The security features of Windows Vista prevent newly generated threats, such as worms, viruses, and malware. In the unlikely event of a successful intrusion, Windows Vista ensures that the degree of

Thanks to its super portability and ease of use, smartphones have increased our daily lives in many ways, providing instant access to rich information on the Internet, as well as the following features: credit card payments, video conferencing and language recognition. According to Gartner, more than 428 million mobile devices were sold around the world in the second quarter of 201

What the general user calls "virus" is not the real virus, in addition to worms, including some malicious software, many people will call malware viruses, such as Trojan horses, access rights tools, users only understand them to know the harm. 　　Malicious software "Malicious operating Software" is referred to as "malicious software". Many people use the word "virus" to explain this type of software, but the virus is only one of them. "

as the definition of "computer virus" in the traditional sense. In fact, currently, mobile phone viruses that fully comply with the definition of "computer viruses" are rare, and they are more likely to appear in the form of Trojans or malware. However, such malware is no less harmful than computer viruses in the traditional sense. trojans such as "couple locating software" can customize fee deduction serv
